Article Synopsis
- High-voltage lithium metal batteries (HV-LMBs) are seen as a key solution for high energy density storage, but existing electrolytes struggle to stabilize both the lithium anode and high-voltage cathodes efficiently.* -
- A new dual-interphase-stabilizing electrolyte is introduced that eliminates the need for expensive Li salts, using a sulfolane solvent and specially designed additives to create stable protective layers for both the anode and cathode.* -
- Testing shows that cells with this electrolyte can last over 500 cycles and deliver a high energy density of 435 Wh/kg, making it a promising option for safer and more cost-effective large-scale battery applications.*
The lithium (Li)-metal anode offers a promising solution for high-energy-density lithium-metal batteries (LMBs). However, the significant volume expansion of the Li metal during charging results in poor cycling stability as a result of the dendritic deposition and broken solid electrolyte interphase. Herein, a facile one-step roll-to-roll fabrication of a zero-volume-expansion Li-metal-composite anode (zeroVE-Li) is proposed to realize high-energy-density LMBs with outstanding electrochemical and mechanical stability.

Such fabric Li–S full batteries offer high volumetric energy density (457.2 Wh L), high-capacity retention (99.

Standard life tables were used to calculate life expectancy and cause-eliminated life expectancy by utilizing mortality data from the national mortality surveillance system. In 2016, the life expectancy of Chinese residents was 78.
